PIGS really do fly - especially when they have Charlie the Crocodile lunging at them.

A packed Crocoseum was treated to a feast of entertainment as the carcass of a feral wild boar was fed to the savage saltie yesterday.

"It's never been done before (in the Crocoseum) so we gave it to him and off he went. It was incredible,'' an animated Bindi Irwin said.

"I think what was so cool was the look in his eye.''

"Yeah, he's just like a dinosaur,'' Bindi's eight-year-old brother Robert chipped in. "He is so massive. He is awesome.''

Not content with the boar, Charlie first snapped at Australia Zoo director Wes Mannion as Terri, Bindi and Robert squealed with delight.

Charlie was in no hurry to wolf down his meal, instead trying to first drown it before 'tenderising' it with his teeth.

Many head slaps helped break up the carcass as Charlie continued to toss it into the air and rip off its limbs, even sending his own teeth flying in the process.

"When they headshake, they can break off bits of the pig so they headshake, headshake, headshake,'' Robert explained just like his dad would have. "They have been doing that for over 65 milion years so they are really cool.''

Robert said he loved to collect the teeth after shows, describing them as 'bullets' which penetrate any prey.

The crowd of mum, dads and kids enjoying the last few days of the school holidays were taken in by gruesome feast.

While the zoo's crocodiles are normally fed smaller animals like chickens, a large male crocodile is capable of taking on a food item as large as a one tonne water buffalo.

Over the holidays, Bindi has been feeding rats to the crocodiles under the watchful eye of Wes and Terri.

Little Robert has been told he has to wait until he's a little older to join the action.

The well known Coast family plan to be back in action for the Zoo's big Australia Day show next week before heading off on myriad overseas assignments.

A Zoo spokesperson said the Coast's biggest employer had enjoyed a "really good'' summer with bumper crowds loving the new Africa exhibit.
